How to set the invoice name value using business rules

Hi,

I want to automatically set the  invoice Name eqal to the invoice ID when the user creates an invoice.

I want to use business rules if possible.

Thank you !

I created a business rule like below for the invoice Name but it still taking "New Invoice" ! : 

CONDITION

If Name does not contain data

or Name equals "New Invoice"

ACTION

Set Name to Invoice ID
